Subject: [PATCH] t/op/taint.t: Perform SHA-256 algorithm by crypt() if default
one is disabled
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The crypt(3) call may return NULL. This is the case on FIPS-enabled
platforms. Then "tainted crypt" test would fail.
See RT#121591 for similar fix in t/op/crypt.t.
